Product details

16-bit RL78/G23 MCU with integrated capacitive touch and wide supply range

The Renesas R7F100GEH2DNP#HA0 is a 16-bit RL78/G23 microcontroller built around the RL78 core, running at 32 MHz. It carries 192 KB of Flash program memory, 20 KB of RAM, and 8 KB of data EEPROM, which covers most mid-range control applications without needing external nonvolatile storage. The integrated capacitive touch sensing unit (Capacitive Touch, LVD, POR, PWM, WDT peripherals) allows direct touch-button or slider interfaces, eliminating a separate touch controller IC. The wide supply range of 1.6 V to 5.5 V simplifies power rail design — it can run from a single Li-ion cell or a 5 V industrial rail without a regulator.

The 192 KB Flash (192K x 8) is sized for application code plus a bootloader; the 8 KB EEPROM (8K x 8) holds calibration constants, configuration parameters, or production data that must survive power cycles. The 20 KB RAM provides enough headroom for real-time control loops and moderate communication buffers (CSI, I²C, LINbus, SPI, UART/USART).

Capacitive touch — no external controller needed

The RL78/G23 peripheral set includes a capacitive touch sensing unit that can drive touch buttons, sliders, or wheels directly through the MCU's I/O pins. This eliminates a dedicated touch controller IC and its associated firmware overhead. The peripheral is supported by Renesas' touch evaluation suite, which simplifies tuning for sensitivity and noise immunity.

40-WFQFN exposed pad — thermal and layout considerations

The 40-WFQFN exposed pad package (6x6 mm body) requires a thermal pad on the PCB for heat dissipation. The 33 I/O count is adequate for sensor interfaces, display segments, or keypad scanning in a compact footprint.

The RL78/G23 series is a current-generation platform, so PCN notifications are expected to follow standard Renesas notification timelines.

Frequently asked questions

Where can I find the datasheet for R7F100GEH2DNP#HA0?

The datasheet is available from Renesas' official website under the RL78/G23 series documentation. The part number is listed as R7F100GEH2DNP#HA0. The datasheet covers the full electrical characteristics, pin assignments, and application notes for the 40-WFQFN package variant.

What is the flash memory size of R7F100GEH2DNP#HA0?

The program memory is 192 KB (192K x 8) of Flash. This is sufficient for mid-range control firmware, including a bootloader and application code for capacitive touch, communication stacks, and sensor processing.

Can R7F100GEH2DNP#HA0 be used for capacitive touch sensing?

Yes. The MCU includes a capacitive touch peripheral (Capacitive Touch, LVD, POR, PWM, WDT) that supports touch buttons, sliders, and wheels without an external touch controller. The RL78/G23 series is specifically designed for human-machine interface applications.

Is R7F100GEH2DNP#HA0 compatible with the RL78/G23 starter kit?

The RL78/G23 starter kit (e.g., RTK7RLG230xxxxxx) supports the RL78/G23 series in various packages. The 40-WFQFN variant may require a specific adapter board or socket for the starter kit's main board. Check the starter kit documentation for supported package types.

What is the replacement or alternative for R7F100GEH2DNP#HA0?

A pin-compatible alternative within the same RL78/G23 family is the R7F100GEH2DNP#AA0, which differs only in the shipping medium (Tray vs Tape & Reel). The R7F100GFK2DFP#AA0 provides 37 I/O in a 48-pin LQFP. All share the same RL78 core, 32 MHz speed, and peripheral set.
